Fig. 12 is a view looking in the direction of the line l2 I2 of Fig, 9.

Fig. 13 is a View similar to Fig. 12 but illustrating a still further position of the parts.

The automatic self-closing window ventilator includes a frame I Il for engagement under a window opening. The frame Ill is constructed of wood or other material and is adapted to be at the window frame and held in position by suitable brackets IB at one end of the window II.

A panel is hingedly mounted at its bottom edge on the frame IQ and is capable of extending across the frame for closing the same. The pan? el comprises a wooden frame I2 which has a pane of glass I3 iixedly mounted therein. tom edge of the panel frame I2 is hingedly supported upon a portion of the frame IU by means of hinges It. The panelv is adapted to be ex'- tended to the position illustrated by the full lines in Figs. 2 and '7 for permitting air to pass through the opening in the frame to the inside of the room. The panel is also capable of being moved to the position illustrated by the dot and dash lines in Fig. 7, or the full lines in Fig. 6 to close the opening in the frame I Il when so desired.

A pair of links I5 are pivotally connected together at their inner ends andpivotally connected at their outer ends to said panel and the frame I0, respectively, and adapted to fold to a closed position when the panel closes said frame. The links I comprise separate pieces of metal i5a and lh which are pivotally connected together at their inner ends by means of a pin I6. The link is pivotally supporte-d at its outer end upon a portion of the frame Iii by means of a pin I1. The link I5a has its outer end pivotally supported on a block I8 by means of a pin I9. This block I8 is xedly attached to a strip of metal 2l) Which is adapted to extend along the edge portion of the frame I2 forming a portion of the said panel. Screws 2l pass through openings formed in the ends of the strip of metalZ and threadedly engage into the frame I2 forming the panel for xedly supporting this strip thereon.

Resilient means is provided for urging the panel against the frame Ill for closing the same and comprises a spring 22 coaxially mounted upon The botthe pivot point of the hinges I4 and having one of its ends engaging against the bottom edge of the frame l2 which forms a portion of the panel, and the other of its ends engaging against the outer face of the frame Il! for normally urging the panel into its closed position shown by the dot and dash lines I2 in Fig. 7, and the full lines in Fig. 6.

A finger 23 is rigidly mounted on the link adjacent the panel and comprises a member substantially L-shaped in construction and having one of its arms iixedly attached to the inner end of the link [5a which is pivotally supported upon the panel. The other arm of the nger 23 is formed with an enlarged head 23a, in the form of a roller.

A hook 24 is pivotally mounted on the frame l0 and is cooperative with the linger 23 to releasably hold the said nger to hold the panel in its open position. The hook 24 comprises a strip of metal or other similar material which is formed intermediate of its ends with outwardly extending lugs 24a. A plate 25 is formed at its ends with openings through which screws 26 pass for xedly attaching the plate 25 to a portion of the frame I0. This strip 25 is also formed with outwardly extending lugs 2F:a which are adapted to extend along the sidesv of the lugs 24a. A pin 26 passes `through the lugs 24a and 25a for pivotally supporting the hook 24 upon the strip 25. The upper end of the strip of metal forming the hook 24 is bent into substantially hook shape 24D beneath which the enlarged roller head 23a in the :form of a roller of the nger 23 is adapted to be engaged for extending the links l5 to hold the panel in its open position.

A clock-controlled means is provided for pivoting the hook 24 to release the nger 23 so that the spring 22 may urge the panel into its closed position with relation to the frame l. 'Ihe clock controlled means comprises a clock 21 of conventional construction which is flxedly attached to an arm 25h extending from the plate 25. The clock 2l is formed with a handle 21a which is adapted to be rotated for winding the main spring 2lb thereof to cause the clock to operate in the usual manner.` The time mechanism has an hour spindle which extends from the front thereof. A dial 28 is mounted on the hour spindle and is formed with a cam 28a which is adapted to strike against the bottom portion 24c of the hook 24 for pivoting the hook 24 to release the iinger 23. The dial 28 is imprinted with numbers from zero to Il along its outer edges and which are adapted to be viewed through a window opening 2S formed in a portion of the frame I0.

A knob 3D extends from the end of the hour mechanism and is adapted to be manually rotated for setting the dial 28 toits desired predetermined positions for controlling the amount of time which must elapse before the cam 28a will strike the bottom portion 24 of the hook 24. If it is desired to have nine hours elapse before the panel is closed the knob 30 is rotated until the number 9 on the dial may be viewed through the window opening 29, as shown in Fig. 1. The dial 2B will then be rotated in a direction shown by the arrow 3l in Fig. 4,and after nine Vhours will reach the dot and dash position 28b shown in Fig. 4 and pivot the hook 24 as shown by the dot and dash lines 24 in the said Fig. 4. The finger 23 will then be freed by the hook and the spring 22 will urge the panel closed.

Glass strips 32 Iare engaged into brackets 33 which are attached to the edges of the opening in the frame I0. These glass strips are at the ends of the opening in the frame I0, as clearly shown in Fig. 3, and act to prevent rain or snow from getting within the room.

The operation of the device is as follows: The knob 30 is rotated until the desired predetermined time is positioned within the opening 29 and the panel is moved to the open position and the enlarged head 23a is engaged beneath the hook element 24b of the hook 24. The person then goes to sleep or follows his ordinary routine, and the clock mechanism 21 will rotate the dial and when the predetermined position is reached the cam 28a will strike the bottom portion 24c of the hook 24 and pivot the hook to the dot and dash positions 24' shown in Fig. 4 to free the enlarged head 232L of the nger 23. When this finger is released the spring 22 will urge the panel into its closed position as shown by the full lines `in Fig. 6.

According to the modications shown in Figs. 9-13 a means is provided for adjusting the mechanism to hold the panel open to diierent degrees. The hook 24 is formed with enlarged elongated lugs 24" which are formed with elongated slots 40 through which the pin 26 passes. The hook 24 may be moved vertically by shifting the position of the pin 26 Within the slot 4G for adjustably supporting the hook 24 upon the plate 25. The elongated slots 40 are formed with aligned oiset portions 40a into which the pin 2B is adapted to engage and about which the hook 24 pivots. A spring 4l has one of its ends bearing against the bottom face of the hook 24 for urging the said hook into a position in which the pin 26 will engage the offset portions 40a of the slots 40.

'I'he nger 23 is rigidly adjustably supported upon the link l5a so that it may be adjusted with relation to different positions of the links so that the arm upon which the roller head is mounted may always be in the horizontal position so that it may be engaged beneath the hook element 24h of the hook 24. The enlarged head 23 is threadedly supported upon the end of one of the arms of the nger 23 so that it may be moved along the length thereof to properly engage the hook element 241.

The means for rigidly adjustably supporting the nger 23' upon the link I5Et comprises a disc 42 attached to the inner face of the finger 23' and which is adapted to abut an adjacent disc 43 supported on the end of the link |53. A pin 44 extends from the disc 43 and passes through openings formed in the disc 42 and the adjacent portion of the finger 23' and is formed at its inner end With an enlarged head 44a. A spring 45 has one of its ends acting against the finger 23' and the other of its ends acting against the head 44a for urging the disc 42 against the disc 43. The disc 42 is formed with a serratedportion 112iL which is adapted to engage complementary serrations 43a formed on the adjacent face of the disc 43. When the serrations 42a and 4?a are interengaged with each other the nger 23 is rigidly supported upon the link I5a.

The operation of` this form of the device is as follows:

The position of the parts as shown in Fig. 9 is similar to that shown in Fig. 7 in which the panel is fully open with relation to the frame l0. When it is desiredto have the panel only slightly open withrelation to the frame I0 as shown in Fig. 10, the hook 24 is moved upwards, as shown a by the full lines in Fig. l and the dot and dash lines in Fig. 11. This is accomplished by pressing inwards on the outer face of the hook 24 to disengage the pin 26'l from the oii'set portions lila of the slots 40. The hook 24 may then be moved upwards with relation to the pin 26', and when the pressure is again released the spring lll will urge the hook 24 into ya position in which the lowermost offset portions 402 Will engage the pin I() 26'. The panel is then opened the desired amount and the linger 23 is adjusted upon the link lila so that the enlarged head 23" will be horizontal with relation to the hook element 24h. This is accomplished by urging the ringer 23' outwards to disengage the serrations Za and 43a so that the iinger may be rotated upon the pin 413 to the desired position. 'Ihe finger is again released and the spring 45 will urge the nger 23 to a position in which the serrations 42a and [43a will again be intereengaged for rigidly supporting the finger upon the link la.

'Ihe enlarged head 23" is then moved 'inwards with relation to the end of the finger 23 so that it will be engaged beneath the hood element 241 25 and the device is set -for holding the panel open slightly as shown in Fig. l0. The procedure is now similar to that described in connection with the form shown in Figs. 1 8. When the cam 28a strikes against the bottom portion 26C of the 30 hook 24 it Will release the iinger 23' and permit the panel to be closed by the spring 22.

While I have illustrated and described the preferred embodimentsof my invention, it is to be understood that I do not `limit myself to the 85 precise constructions herein disclosed and the right is reservedto all changes and modications coming Within the scope of the invention as defined in the appended claims.

Having thus described my invention, what Il claim as new, and desire to secure by United.
